Purpose: Pediatricians have a significant responsibility to educate mothers about the importance of breastfeeding. However, there have been minimal efforts in the courses of resident training in Korea. The purpose of this study is to evaluate the change in knowledge and attitude before and after a 4-week breastfeeding educational intervention among multicenter residents. Methods: Prospective interventional educational research was designed for residents at eight training hospitals in Korea. Institutional reviews were obtained in each hospital. The education curriculum consisted of 14 courses regarding breastfeeding theory and practice. These materials were used to teach pediatric residents for 4 weeks. Knowledge-based tests were administered before the course, and re-tests were administered after the course using different test items of similar levels. Test scores and survey responses were compared before and after the intervention. Results: A total of 73 residents (1st year 20, 2nd year 23, 3rd year 16, and 4th year residents 14) from eight training hospitals completed the intervention. Their average age was 30.3±2.9 years, 17 (23.3%) were male, 22 (30.1%) were married, and eight had more than one child of their own. The mean pre-test score was 61.8±13.4 and the mean post-test score was 78.3±7.5 (P<0.001). The inter-grade difference in the score was significant in the pre-test (P=0.005), but not significant in the post-test (P=0.155). There were more responses of obtaining confidence after the intervention (P<0.001). Conclusion: In our study, pediatric residents showed improvement in their knowledge and confidence level after 4 weeks of the breastfeeding curriculum. This will provide a basis for future policymaking in the training of pediatric residents regarding breastfeedReceived: 6 January 2022 Revised: 15 February 2022 Accepted: 15 February 2022 Correspondence to: Ellen Ai-Rhan Kim, MD Department of Pediatrics, Asan Medical Center, University of Ulsan College of Medicine, 88 Olympic-ro 43-gil, Songpa-gu, Seoul 05505, Korea Tel: +82-2-3010-3390 Fax: +82-2-3010-6978 E-mail: arkim@amc.seoul.kr A Multi-Center Educational Research Regarding Breastfeeding for Pediatrics Residents in Korea Yong-Sung Choi, MD,PhD1, Sung-Hoon Chung, MD, PhD2, Eun Sun Kim, MD, PhD3, Eun Hee Lee, MD4, Euiseok Jung, MD5, So Yeon Lee, MD, PhD5, Wooryoung Lee, MD6, Hye Sun Yoon, MD, PhD7, Yong Joo Kim, MD, PhD8, Ji Kyoung Park, MD, PhD9, Son Moon Shin, MD, PhD9, and Ellen Ai-Rhan Kim, MD, PhD5 1Department of Pediatrics, Kyung Hee University Hospital, Seoul, Korea 2Department of Pediatrics, Kyung Hee University Hospital at Gangdong, Seoul, Korea 3Department of Pediatrics, Kangwon National University Hospital, Chuncheon, Korea 4Department of Pediatrics, Korea University Anam Hospital, Seoul, Korea 5Department of Pediatrics, Asan Medical Center, University of Ulsan College of Medicine, Seoul, Korea 6Department of Pediatrics, Soonchunhyang University Seoul Hospital, Seoul, Korea 7Department of Pediatrics, Nowon Eulji Medical Center, Eulji University, Seoul, Korea 8Department of Pediatrics, Hanyang University Seoul Hospital, Seoul, Korea 9Department of Pediatrics, Inje University Busan Paik Hospital, Busan, Korea Neonatal Med 2022 February;29(1):28-35 https://doi.org/10.5385/nm.2022.29.1.28 pISSN 2287-9412 . eISSN 2287-9803 Copyright(c) 2022 By Korean Society of Neonatology This is an Open-Access article distributed under the terms of the Creative Commons Attribution Non-Commercial License (http:// creativecommons.org/licenses/by-nc/4.0), which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited.

This study was performed to evaluate the effect of persimmon vinegar on serum lipid components in the hypercholesterolemic Sprague-Dawley male rats. Forty rats were divided into four groups and fed diets containing 1% cholesterol for 4 weeks. Experimental diets added to distilled water, 1.5%, 3%, and 7% persimmon vinegar(PV) as drinking water. Concentration of total cholesterol, LDL and HDL cholesterol, triglyceride in serum and activity of AST, ALT in serum were assayed. Average food intake, weight gain and FER of experimental rats were not significantly different by contents of persimmon vinegar. Concentration of total cholesterol and LDL cholesterol in serum were lowest in 7% persimmon vinegar group. However concentration of HDL cholesterol in serum was highest in 3% persimmon vinegar group. Concentration of triglyceride in serum was significantly lower in persimmon vinegar group than control group. Activities of AST and ALT in serum were lowest in 7% persimmon vinegar group. The results in this study suggest that persimmon vinegar is effective in lowering serum triglyceride level.

This paper is to study the influence of the billboard color design as we perceive the city streetscape. It consists of two parts in that process. The first is about how to determine the color which is the basis of this study. A simple and accurate method is proposed which is appropriate in this digitized age. Second, we analyze the differences in color of each surveyed district, eliciting a color image map which would reflect the impact of billboard colors on the street. The finding of this study could be of a help in guiding the improved billboard color in harmony with the streetscape.

Twenty seven pregnant women between 22 and 36 weeks of gestational age presenting with preterm labor, intact membrane and less than 3cm cervical dilatation visited the department of Obstetrics and Gynecology, KonKuk University Medical Center, Choongju Hospital from June 1, 1998 to March 31, 1999. These patients' cervicovaginal swabs were assessed for the presence or absence of fetal fibronectin by means of ROM-CHECK(monoclonal antibody assay) the positivity of which was revealed by a colorimetric reaction. Also cervical parameters such as cervical length, presence of funneling, funnel length and funnel width were measured by transvaginal ultrasonography. We compared the diagnostic performances of these results in the prediction of preterm delivery of patients with preterm labor and intact membranes. The results were as follows; 1. The overall incidence of preterm delivery(< 37 weeks) was 44%; 12 among 27 patients. 2. There were statistically significant differences in the mean Bishop scores(4.58±0.48 vs 2.13±0.36), the mean gestational age at first admission with preterm labor(33.33±0.38 vs 29.47±1.06 weeks), the mean gestational age at delivery(34.92±0.34 vs 38.27±0.34 weeks) and interval from first admission to delivery(284.2±103.1 vs 1,339.2±154.4 hour) and mean birthweight(2,620±100 vs 3,131±100g) between the preterm delivery group and term delivery group. 3. The positive rates of fetal fibronectin in the vaginal fluid of preterm delivery group and term delivery group were 42%(5/12) and 0%(0/15). 4. The mean cervical length, presence of cervical funneling, funnel length and funnel width were 22.25±2.61mm vs 30.67±1.63mm; 75%(9/12) vs 47%(7/15); 11.83±3.40mm vs 4.53±1.64mm; 11.50±2.92mm vs 6.07±1.87mm in preterm delivery group and term delivery group, and there were statistical significances in the mean values of cervical length and funnel length between each group. 5. The sensitivities and specificities of fetal fibronectin, cervical length(≤25mm), cervical funnel length(≥10mm) and width(≥16mm) as a predictor of preterm delivery were 42% and 100%; 75% and 80%: 50% and 87%; 33% and 93%. The positive predictive values and negative predictive values of fetal fibronectin, cervical length(≤25mm), cervical funnel length(≥10mm) and funnel width(≥16mm) as a predictor of preterm delivery were 100% and 68%; 75% and 80%; 75% and 68%; 80% and 64%. 6. The sensitivities and specificities of the combined use of fetal fibronectin, cervical length(≤25mm), cervical funnel length(≥10mm) and width(≥16mm) as a predictor of preterm delivery were 83% and 67%. The positive predictive value and negative predictive value of the combination of fetal fibronectin, cervical length(≤25mm), cervical funnel length(≥10mm) and width(≥16mm) as a whole as a predictor of preterm delivery were 67% and 83%.

Bacillus cereus KCTC 3674 produced at least two kinds of extracellular proteases. Two major bands of the protease activity with molecular weights of approximately 100 and 38 kDa were obtained after gelatin-SDS-PAGE. The production of extracellular proteases occurred during the logarithmic growth phase and was greatest when cultures reached the stationary growth phase. On the other hand, the growth of B. cereus KCTC 3674 and the production of its extracellular proteases were severely inhibited by the addition of protonophore carbonylcyanide m-chlorophenylhydrazone (CCCP). Thus, it was concluded that the growth of B. cereus KCTC 3674 and the production of its extracellular pretenses were strongly affected by a H+ electrochemical potential.

Bilateral diaphragmatic paralysis(BDP) is a rare disorder, which can be secondary to spinal cord injury, motor neuron disease, myopathy, noninfectious polyneuropathy, infection, iced saline cardioplegia performed during cardiac surgery, or idiopathic causes. There may be typical presentations such as dyspnea, paradoxical respiratory movement, and hypercapnic respiratory failure. It needs to exclude above secondary causes to consider idiopathic bilateral diaphragmatic paralysis. We report a 51-years-old man who presented with idiopathic bilateral diaphragmatic paralysis combined with acute pancreatitis. We couldn't find out the association of these two clinical conditions. The patient was improved by mechanical ventilation.

Objectives : Assuming that somatization closely interacts with anxiety symptoms, one might speculate that anxiety symptoms will produce the significant differences in development, course and treatment of somatization and the cause of these differences will be elucidated in the cognitive aspect. This study was performed to examine the cognitive characteristics in terms of the somatosensory amplification and the symptom interaction in patients with somatization accompanied by anxiety symptoms. Methods : The following measures were administered to subjects who had a T-score of >60 on somatization subscale of Symptom Checklist-90-Revision (SCL-90-R) : 1) Minnessota Multiphasic Personality Inventory-Korean Version (MMPI-K), 2) Somato-sensory Amplification Scale (SSAS), 3) Symptom Interpretation Questionnaire (SIQ). There was a comparison of differences in the somatosensory amplification and the symptom interpretation between the anxiety group and the non-anxiety group divided by T-score of >60 on the psychasthenia subscale of MMSE-K. Multiple regression analysis was performed to determine the effect of the differences in the somatosensory amplification and the symptom interpretation on age, sex, marital status and level of education between those two groups. Results : There was a greater amplification of sensation in the anxiety group than the non-anxiety group. The former showed a higher level of physical, psychological and catastrophic interpretation than non-anxiety group except with regard to environ-mental interpretation. Somatization was affected by somatosensory amplification and physical interpretation in both groups, as well as psychological interpretation in the anxiety group. Conelusion : Regarding the cognitive aspect, the somatosensory amplification and symptom interpretation were more severely distorted in patients accompanied by anxiety symptoms. These results suggest that a therapeutic approach based on the cognitive charactehstics is essential for the effective management of somatizer.

Objectives : Mild cognitive impairment (MCI) is distinguished from mild dementia by an absence of global intellectual deterioration and the preservation of activities of daily living (ADL). Recently, however, it became apparent that impairment of instrumental activities of daily living (IADL) is present before the threshold of dementia is reached. Thus, we want to examine whether IADL are impaired in patients with MCI, and which items of IADL are particularly involved. We divided the MCI group into amnestic (aMCI) and non-amnestic MCI (naMCI), and compared to the cognitively nonnal controls. In this study, we focused on the instrumental activities of daily living (IADL). Methods : The sample consisted of 69 community-dwelling older adults from a welfare center for the aged in Korea. The subjects were divided into three diagnostic groups; aMCI [N=19, memory domains below -1.5 standard deviation (SD)], naMCI (N= 19, other cognitive domains below -1.5 SD, except memory domains) and cognitive normal controls (N=31). Subjects were assessed both on IADL and the cognitive function. In order to assess the IADL, we used the Seoul -Instrumental Activities of Daily Living (S-IADL). Included measures of cognitive tests are as follows ; Seoul Verbal Learning Test (SVLT), Rey Complex Figure Test (RCFT), Korean-Boston Naming Test (K-BNT), Stroop test, and Korean-Mini Mental Status Examination (K-MMSE). Groups were compared on the S-IADL and the cognitive tests. Results : The three groups did not differ in the mean age, gender distribution and years of education. S-IADL were shown to be different between the groups in this study. Suects with aMCI were significantly more impaired in S-IADL in comparison to the controls [F (2,50) = 4.251, P=0.020]. And on four items ofS-IADL (shopping, transportation, medication and talking about recent events), subjects with aMCI showed higher impairment compared to the controls. However, the S-IADL did not differ between the subjects with naMCI and controls. Conclusion : In this study, impairment of S-IADL was shown in subjects with aMCI. And S-IADL ofnaMCI was not Significantly differed from aMCI and controls. The results suggest that naMCI would be distinguished from aMCI in characteristics and prognosis.

Objectives : The purpose of this study was to determine the factors affecting smoking cessation rate of heavy smokers. Methods : Typically, 81 participants enrolled in the smoking cessation camp at Chungbuk National University Hospital from April 2016 to November 2016 were included in the present study. The psychological factors related to group classification and the factors related to the success of smoking cessation were analyzed. Results : After 24 weeks of leaving the camp, 57 out of 81 participants successfully quit smoking and 24 failed in doing so. In the successful group, depression scale, stress scale, and various smoking-related factors exhibited intercorrelation and in the failure group, no significant correlation was observed. However, a comparison of correlation coefficients showed no significant difference. In addition, smoking cessation success rate was low when exhaled CO concentration was high at the time of admission when the smoking initiation age was juvenile, and when the smoking type was A (stimulus seeking type). Conclusion : Exhaled CO concentration at the time of admission, smoking initiation age, and smoking type A (stimulus seeking type) were associated with smoking cessation success.
